Applicatiomfiled October 27, 1920.; Serial No. 420,001.

To all whom it may concern;

Beit known that I, SPIRo DENIS GARBIs, asubjeot of His Majesty the King of Greece, and whose address is 90 Lower, Circular road, Calcutta, British India, have invented Mouthpieces for Liquid-Receptacles, of which the following is a specification.

The object of this invention is an im-' proved cap or mouthpiece for apetrol tinor jammed onto the mouthpiece and the tin cannot be easilyopened." The usual-method of sealing adopted is to use a piece of wire passing through some part of f the cap secured with a lead seal in such a way that the cap cannot be opened until the seal is broken.

In breaking the wirethe little leadseal is itself usually thrown away so that there is a small recurring expensein. replacing these seals each; time the tinqis. refilled.

The object of this invention is to provide a type of cap which cannot be stolen.

Another objectis to provide a type of seal which need not be broken to extract the contents of the tin and which seal will in general return to the firm refilling the tin. The

lead of the seal can thus be recovered, and the wire also if desired, thus avoiding even the little loss which the provision of new lead seals at each refilling entails.

In closing the tin a disk of lead, leather, rubber or any other suitable material is used. This disk is protected against damage by the projecting edge of the mouthpiece, but can be easily pierced with a blunt tool like a screw-driver, cut out with a pen-knife or otherwise punctured. Such puncturlng of the closing disk is immediately apparent to the eye. I

The closing disk may be inserted by bending it and depressing it into the mouthpiece and springing it into place, the fastening being slackened back a suitable amount to allow of this being done.

A preferred arrangement however, is by providing a slot through the side of the mouthpiece approximately level with the top by rail whenthe tins are being of the upper surface ofthe tin itself, such slot being-wide enough for the closing disk to beslipped into, place from the side. i

The closing disk; is heldin position by a' screw down fasteningring whichis itself sealed by the wire andlead seal referred to above. The, extractioncf the contents of the tin can only occur ifeither the closing disk is punctured or the fastening ring is tampered with. a

The fastening ring may be provided with one or more small rings,'knobs or other means to or maybe fastenedor looped before through the holes in the piece. By

passin sides of. the mouth fastening rin a until the sealis broken.

' l .y invention will be described with ref erence tothe accompanyingdrawings in; which like numbers of reference indicate like parts throughoutyand in which Figurel is a part plan and :part sectional plan of the apparatus; w i

Fig. 2 is a secti'on'al'elevationof the same. "In these figures the mouthpiece 1 hasa cylindrical part nallyi to take a fastening ring 5. This fasteningring is prevented from being removed internally PIOJQClZlIlg flange altogether by an 4-. A bottom flange 6 is soldered or otherwise secured to the inner end of the mouthpiece or may be one piece with the same and provides the shoulder against which the fastening ring presses the closing disk 7. This closing disk may be made of lead, leather or any suitable substance to prevent leakage of the contents of the tin.

The mouthpiece is soldered into the top of the tin, can or receptacle 8 to which it be applied.

Various methods may be provided for unscrewing the fastening ring 5 sufiiciently to release the closing disk 7 when the same is to be renewed when filled.

One such method is shown at 9,9 on Fig. 1. In this modification a number of outwardly extending notches are made in the interior surface of the fastening ring into which notches a convenient instrument can be fitted to turn the ring.

According to another modification a slot or notch 10 may be made in the upper sur- Patented July 12, 1921.

around which the sealing wire putting a strain I on such wire beforesealing the slackening back of the be absolutely prevented 2 which is screwed inter is to holes 12, 12 may be into which the end of a screw-driver can purpose.

In another modification holes 11 may be made in the ring into which holes the ends of some spring actuated instrument may fit adapted to unscrew the ring. 4

F or sealing the ring two or more small provided which may be positioned so as to be clear only when the fastening ring isscrewed down securely onto the closing disk. Through these holes the ends of a piece of wire may be passed, the ends twisted together and a lead or other seal applied in the usual manner. If preferred this seal can-be arranged to lie in side the mouth of the mouthpiece itself.

One or more small rings,'projections or other means 13 may be provided on the fastening ring 5 to or around which'the wire of the seal may be passed before the same is passed through the holes 12. If more than one of these means13 are provided there will always be one conveniently placed so that the wire of the seal may be looped around the same and twisted so as to be tightened in such a mannerthat a slackening back of the fastening ring is altogether pre vented until the seal is broken.

It will be noted that the provision of these means f 13 allows of a certain amount of latitude in'thepositioning of the holes 12, whichis a distinct advantage.

A slot 14 ma be provided through the side of the mouthpiecethrough which the closing'disk 7 may be inserted.

It will be obvious that there are other simple ways of sealing the fastening ring in position and I do not confine myself to tle use of only the modification mentioned a ove.

,and the manner in which performed, I declare that what I claim is I do not confine myself to the use of this cap to petrol tins only. It may be adapted for use with milk bottles or with cans or other receptacles for holding liquids.

Having now particularly described and ascertained the nature of my said invention the same is to be 1. Amouthpiece with means for closing the same adapted for use with receptacles for holding liquids, ing' an internally-screwed cylindrical part, a fastening ring adapted to engage such internal screw thread, an inwardly projecting flange on the outer or exterior end of the cylindrical portion to prevent removal of the fastening ring, aninwardly projecting flange at the inner orinterior end ofthe cylindrical part adapted to form a shoulder against which the fastening ring may com:

press and hold a closing disk of suitable material.

'2; A- mouthpiece according to claim 1:, with means whereb T the same can be sealed in such amanner that the fastenirig'ring disk, and a closing cannot be slacked back toallow of the contents of the receptacle being ezitracted unless such sealingmeansis broken, substantially as herein described. i

3. With a mouthpiece according to claim the use ofa closing disk made of material wh1ch will retain the contents of the tin. but which can be readily punctured in 0r-' der to extract such contents.

4L. A mouthpiece accordlng to 1 but further characterized by having a slot substantially as herein described through which the closing disk may be introduced.
